Basis of Consideration

The consideration for the Acquisitions under the Share Purchase Agreements was determined after arm’s length negotiations between the Purchaser and the relevant Seller with reference to the per-share amount of the appraised value of TuXi Tech. According to the valuation report (the “Valuation Report”) dated June 15, 2026 issued by China Alliance Appraisal (Shanghai) Co., Ltd. (中同華資產評估(上海)有限公司) (the “Valuer”), an independent valuer, the appraised value of the entire shareholders’ equity of TuXi Tech as at the Valuation Benchmark Date (being December 31, 2025) using asset-based approach was approximately RMB3,613,527,700. Further details of the Valuation Report are set out in the section headed “The Valuation Report” in this announcement.

The Group will settle the consideration for the Acquisitions with its internal resources.

THE VALUATIONREPORT

Selection ofValuation Approach for the Valuation

In the Valuation Report, the Valuer has considered the application of three basic valuation approaches, namely the market approach, income approach and asset-based approach.

The application of the market approach requires: (i) a public market and active trading for comparable references of the subject entity; and (ii) access to transaction information. TuXi Tech is an offshore holding platform with no actual business operations. It is difficult to find sufficient comparable transaction cases for the subject entity in either the capital markets or the property rights trading markets. Therefore, the market approach is not applicable.

The application of the income approach requires: (i) the future return of the valuation subject can be reasonably anticipated and measured in monetary terms; (ii) the risks associated with the expected return can be quantified; and (iii) the return period can be determined or reasonably estimated. TuXi Tech is an offshore holding platform with no actual business operations. Future expected returns cannot be reasonably determined. Therefore, the income approach is not applicable.

The application of the asset-based approach requires that: (i) the valuation subject is in normal use or currently in use; (ii) the valuation subject can be obtained through replacement channels; and (iii) the replacement cost of the valuation subject and related depreciation can be reasonably estimated. The assets and liabilities listed on the balance sheet of TuXi Tech as of the Valuation Benchmark Date can be identified and valued individually using appropriate methods. Therefore, the asset-based approach is applicable.

Considering the purpose of this Valuation and the characteristics of the subject entity, combined with the above analysis, the asset-based approach was adopted for this Valuation. The total equity value of TuXi Tech pursuant to the asset-based approach valuation is approximately RMB3,613,527,700. Further details of the Valuation Report containing, among other things, the principal assumptions, valuation model and inputs used in the preparation of such valuation, are set out in Appendix I to this announcement.

Valuation approachesin respect of Tuxi Xiamen

In arriving at the appraised value of TuXi Tech, the Valuation in respect of the long-term equity investment in TuXi Xiamen, a wholly owned subsidiary of TuXi Tech, was conducted using both the income approach and the market approach, with the valuation results from the income approach adopted in the valuation conclusion of Tuxi Xiamen.

The income approach considers the enterprise’s future earning capacity and reflects the comprehensive profitability of its various assets. TuXi Xiamen is a company with high profitability; its expected returns are quantifiable, the duration of expected returns is predictable, and the risks associated with these returns, which are closely related to discounting, are foreseeable. Therefore, the income approach is appropriate for the Valuation in respect of the long-term equity investment in TuXi Xiamen. The valuation methodology involves forecasting the operations of all business entities within the scope of consolidation to generate a consolidated income statement and calculate cash flows on a consolidated basis.

As a provider of last-mile post, TuXi Xiamen has, through years of accumulation, established a mature operational network. Its intangible resources, including customer base, logistics network, talent pool, and management expertise, are difficult to measure and quantify individually under the asset-based approach. Furthermore, the asset-based approach fails to capture the value derived from the synergistic interaction of various assets within TuXi Xiamen’s operations. Consequently, the asset-based approach cannot fully reflect TuXi Xiamen’s true value and thus is not applicable in the Valuation in respect of the long-term equity investment in TuXi Xiamen.

Both TuXi Xiamen and its upstream and downstream industries contain listed companies. Among these listed companies, there are a sufficient number of entities comparable to the subject entity. Furthermore, relevant data regarding the operating conditions, financial data, and market share prices of these comparable companies are generally available through public markets and channels. This provides the necessary conditions for data collection and quantitative analysis of relevant differences. Therefore, the market approach is applicable in the Valuation in respect of the long-term equity investment in TuXi Xiamen.

Selection ofvaluation results in respect of Tuxi Xiamen

Based on the following factors, the results of the income approach were adopted as the valuation conclusion for the long-term equity investment in TuXi Xiamen.

(i)	The<br> income approach considers the future profitability of TuXi Xiamen and reflects the comprehensive<br> profitability of its various assets. TuXi Xiamen is not a manufacturing enterprise. Its core<br> value is comprehensively reflected in the extensive industry experience of its management<br> team, quality customer resources and logistics channels, and the strong market reputation<br> it has established since its inception, which are not reflected in its financial statements.<br> The income approach takes into account the above factors that have a significant impact on<br> its profitability. TuXi Xiamen is expected to have good business prospects, strong profitability,<br> and its asset portfolio is capable of generating corresponding returns.
(ii)	As<br> for the market approach, it derives the value of shareholders’ equity of the subject<br> entity by analyzing various indicators of comparable listed companies, determining the ratios<br> between their equity or enterprise value and certain profitability, asset or other characteristic<br> indicators, and inferring the applicable ratio multiples for the subject entity. Currently,<br> there are slight differences among the sub-segments of vertical application software and<br> certain differences in their principal products. The Valuer understands that the available<br> information on comparable listed companies is relatively limited, and there may be uncertain<br> factors or factors that are difficult to adjust, such as unique intangible assets or contingent<br> liabilities specific to comparable listed companies. This creates a risk that the valuation<br> results under the market approach may deviate significantly from the actual enterprise value.<br> In addition, market fluctuations also contribute to the uncertainty of the results under<br> the market approach.
---	---

(i)

The income approach considers the future profitability of TuXi Xiamen and reflects the comprehensive profitability of its various assets. TuXi Xiamen is not a manufacturing enterprise. Its core value is comprehensively reflected in the extensive industry experience of its management team, quality customer resources and logistics channels, and the strong market reputation it has established since its inception, which are not reflected in its financial statements. The income approach takes into account the above factors that have a significant impact on its profitability. TuXi Xiamen is expected to have good business prospects, strong profitability, and its asset portfolio is capable of generating corresponding returns.

(ii)

As for the market approach, it derives the value of shareholders’ equity of the subject entity by analyzing various indicators of comparable listed companies, determining the ratios between their equity or enterprise value and certain profitability, asset or other characteristic indicators, and inferring the applicable ratio multiples for the subject entity. Currently, there are slight differences among the sub-segments of vertical application software and certain differences in their principal products. The Valuer understands that the available information on comparable listed companies is relatively limited, and there may be uncertain factors or factors that are difficult to adjust, such as unique intangible assets or contingent liabilities specific to comparable listed companies. This creates a risk that the valuation results under the market approach may deviate significantly from the actual enterprise value. In addition, market fluctuations also contribute to the uncertainty of the results under the market approach.

---

The Valuation in respect of TuXi Xiamen was performed involving the income approach which has taken into account the discounted cash flow forecast of TuXi Xiamen and constitutes a profit forecast under Rule 14.61 of the Hong Kong Listing Rules. Therefore, the Company is required to comply with the announcement requirements under Rules 14.60A and 14A.68(7) of the Hong Kong Listing Rules.

Deloitte Touche Tohmatsu, the Company’s reporting accountant, has reported on the arithmetical accuracy of the calculations of the discounted cash flow forecast contained in the Valuation Report. The full text of the report from Deloitte Touche Tohmatsu is contained in Appendix II to this announcement.

The Board has confirmed that the profit forecast was made after due and careful enquiry. The full text of the letter from the Board is contained in Appendix III to this announcement.

Valuer’sBackground and Independence

The Valuer is a professional and qualified valuer in the PRC. Taking into consideration the fact that the Valuer is independent from the Company and its connected persons, and the qualification and experience of the Valuer in business valuations, the Directors are satisfied with the Valuer’s independence and are of the view that the Valuer is competent to conduct the Valuation.

Having considered (i) the independence of the Valuer; and (ii) the basis and approach for the valuation as well as relevant data for arriving at the valuation of TuXi Tech, the Directors (including independent non-executive Directors) are of the view that the consideration is fair and reasonable.

APPENDIX I –FURTHER DETAILS OF THE VALUATION REPORT VALUATION MODEL AND PARAMETERS OF ALL ENTITIES

The asset-basedapproach

In enterprise valuation, the asset-based approach refers to a valuation method that determines the value of the subject entity by assessing the value of all assets and liabilities, both on-balance-sheet and identifiable off-balance-sheet items, as of the Valuation Benchmark Date, based on the subject entity’s balance sheet.

When using the asset-based approach for enterprise valuation, the value of each asset should be determined by selecting an appropriate specific valuation method based on its specific circumstances. The selected valuation methods may differ from those used when the asset is evaluated as an individual item; therefore, their contribution to the enterprise’s value must be taken into account.

The specific valuation methods for various types of assets and liabilities are as follows:

Valuation of current assets

The current assets of the subject entity consist of cash and cash equivalents. Cash and cash equivalents, including bank deposits, are valued based on the verified amounts obtained by reconciling bank statements and verifying confirmation letters sent by the accountant.

The current assets of TuXi Tech comprise its cash and cash equivalents of approximately RMB3.5 million.

Valuation of non-current assets

For long-term equity investments where the investor holds control and the investee is operating normally, the investee is valued as a whole as of the same Valuation Benchmark Date. The valuation of the long-term equity investment is determined by multiplying the investee’s net assets (as determined by the overall valuation) by the investor’s ownership percentage.

The non-current assets of TuXi Tech comprise its long-term equity investments, which represents the long-term equity investment in TuXi Xiamen, as reflected in the financial statements of TuXi Tech. The valuation of TuXi Xiamen is RMB3,610 million. For details of the valuation of TuXi Xiamen, please refer to the section headed “VALUATION MODEL AND PARAMETERS FOR TUXI XIAMEN”.

VALUATION MODELAND PARAMETERS FOR TUXI XIAMEN

The income approach is a valuation method that determines the value of the subject entity by capitalizing or discounting expected future cash flows.

Common specific methods within the income approach include the dividend discount model, the equity free cash flow discount model, and the enterprise free cash flow discount model.

The dividend discount model is typically used to value the equity interests of non-controlling shareholders.

In the discounted free cash flow to equity method, the cash flow metric is the cash flow attributable to shareholders, the corresponding discount rate is the cost of equity capital, and the valuation result represents the total equity value of the shareholders. The cash flow calculation formula is:

EquityFree Cash Flow = Net Income + Depreciation and Amortization – Capital Expenditures – Increase in Working Capital –Principal Repayment of Interest-Bearing Debt + Principal of New Interest-Bearing Debt

Enterprise Free Cash Flow Method: The cash flow metric is the cash flow attributable to all investors, including shareholders and interest-bearing debt creditors. The corresponding discount rate is the weighted average cost of capital (WACC), and the valuation result represents the enterprise’s total value. The cash flow formula is:

EnterpriseFree Cash Flow = Net Income + Depreciation/Amortization + After-Tax Interest Expense – Increase in Working Capital – CapitalExpenditures

This valuation employs the discounted free cash flow model within the discounted cash flow method.

The basic formula is:

E = B −D

Where:E represents the market value of the total equity of the subject entity, D represents the market value of interest-bearing liabilities,and B represents the overall market value of the enterprise.

B =P + Σ Ci

Where:P represents the value of operating assets, and ΣCi represents the value of non-operating assets and liabilities (including surplusassets) existing as of the Valuation Benchmark Date.

Where:

P — thevalue of the enterprise’s operating assets as of the Valuation Benchmark Date; Fi — the expected free cash flow of the enterprisefor the i-th future income period;

Fn+1 —the expected free cash flow of the enterprise in the first year of the perpetual period; r — discount rate; for this valuation,the discount rate is set at 10.60%;

n — thedetailed forecast period, being five years (2026 to 2030); i — the i-th year of the detailed forecast period;

g— perpetual growth rate following the detailed forecast period; for this valuation, the perpetual growth rate is set at 1.00%.

The parameters are determined as follows:

1.	Determination<br> of Free Cash Flow (Fi)

Fi= Net Income + Depreciation/Amortization + After-Tax Interest Expense – Increase in Working Capital – Capital Expenditures

2.	The<br> discount rate r is determined using the weighted average cost of capital (WACC), as shown<br> in the following formula:

Where:Re: cost of equity capital; Rd: cost of debt capital; T: corporate income tax rate.

3.	The<br> cost of equity capital, Re, is calculated using the Capital Asset Pricing Model (CAPM), as<br> shown in the following formula:

Re= Rf + β × ERP + Rs

Where:Re is the cost of equity capital, i.e., the return on equity; Rf is the risk-free rate of return; β is the beta coefficient; ERPis the market risk premium; Rs is the firm-specific risk premium.

The key parameters for the discount rate are determined as follows:
Parameter	Value
Risk-free rate (Rf)		2.33	%
Equity market risk premium (ERP)		6.12	%
Average unlevered beta of comparable companies		0.7295
Target capital structure		11.91	%
Firm-specific risk premium (Rs)		4.00	%
Cost of equity capital (Re)		11.67	%
Cost of debt capital (Rd)		3.50	%
Income tax rate (T)		25	%
WACC		10.60	%

Risk-free rate (Rf)

Using iFinD (同花順) data system (“iFinD”), the Valuer selected publicly traded government bonds listed on the Shanghai and Shenzhen stock exchanges with a remaining maturity of more than 10 years from the valuation base date to the bond’s maturity date. After filtering out certain bonds (e.g., those with abnormal trading patterns and those issued to commercial banks), the Valuer calculated their yield to maturity (YTM) using the compound interest method. The average of the YTMs of all selected government bonds was taken as the risk-free rate for this valuation.

Equity MarketRisk Premium (ERP)

The equity market risk premium represents the return investors expect to earn by investing in the stock market in excess of the risk-free rate. The Valuer chose to calculate the equity market risk premium using historical risk premium data from the China Securities Market Index. Currently, there are numerous indices on the Shanghai and Shenzhen stock exchanges that effectively reflect the risk profile of the Shanghai and Shenzhen securities markets. The reference sample is the CSI 300 Index. Therefore, the Valuer has identified the 300 constituent stocks of the CSI 300 Index as the specific sample for calculating the equity market risk premium. Given the volatility characteristics of the stock market, the Valuer has selected a 10-year period as the calculation horizon for the equity market risk premium. This means that for each constituent stock, the expected future return is determined by calculating its 10-year average return. The Valuer utilizes the iFinD data system, which provides the year-end closing prices for each selected constituent stock as the “back-adjusted” year-end prices in the iFinD database. The Valuer determines the equity market risk premium for each year by calculating the geometric average return over the calculation period and the risk-free interest rate for each year.

Specifically, after calculating the geometric mean of the annual returns for the CSI 300 index constituents, the Valuer needs to average the returns of the 300 stocks to derive the geometric mean for that year. For this calculation, the Valuer uses a weighted average, with the weights corresponding to each constituent’s weighting in the CSI 300 index. Through this estimation, the Valuer can calculate the annual market risk excess return (ERPi) for each of the 10 years within the calculation period. After excluding the maximum and minimum values and taking the average, the Valuer obtains the final equity market risk premium.

Selectionof Comparable Companies

Based on the asset group holder’s core business and operating performance, the Valuer has preliminarily adopted the following basic criteria for selecting comparable companies in this valuation:

(1)	comparable<br> companies must have been listed for at least two years;
(2)	comparable<br> companies must issue only RMB A-shares;
---	---
(3)	the<br> industry in which the comparable company operates or its core business must be the same or<br> similar to that of the asset group holder, or be subject to the same economic factors, and<br> the company must have a history of operating in that industry for at least two years.
---	---

Based on the above three principles, the Valuer utilized the iFinD financial data terminal for screening. After comprehensively considering various factors — including business type, company size, profitability, growth potential, industry competitiveness, and stage of corporate development — the Valuer ultimately selected and identified comparable listed companies.

Capital Structure

The capital structure used in the income approach valuation primarily includes:

(1)	the<br> average capital structure of comparable companies as the target capital structure;
(2)	the<br> actual capital structure of the asset group holder;
---	---
(3)	variable<br> capital structure.
---	---

For this valuation, the average capital structure of comparable companies was selected as the target capital structure.

Beta Coefficient

(1)	The<br> Valuer selected listed companies based on the criteria for comparable companies outlined<br> above and used the β calculator published by iFinD to calculate the β values of<br> the comparable companies. These β values incorporate the comparable companies’<br> own capital structures.
(2)	Using<br> the following formula, the Valuer can calculate the unlevered β for each peer company:
---	---

Unlevered β = Leveredβ/[1 + (1 – T) × D/E]

Where: D = Debt value;E = Equity value; T = Applicable income tax rate.

After calculating the unlevered β for the comparable companies, take their average as the unlevered β for the asset group holder.

(3)	Next,<br> substitute the determined capital structure ratios of the asset group holder into the following<br> formula to calculate the asset group holder’s Levered β:

Levered β = Unleveredβ × [1 + (1 – T) × D/E]

Where: D – Debt value;E – Equity value; T – Applicable income tax rate;

(4)	The<br> purpose of estimating the β coefficient is to determine the discount rate used to discount<br> future expected returns; therefore, the discount rate should reflect future expectations,<br> and consequently, the estimated β coefficient must also represent a future expected<br> β coefficient.

The method the Valuer uses to estimate the β coefficient relies on historical data; consequently, the β coefficient the Valuer actually estimates is a historical β coefficient rather than a future expected β coefficient. To estimate the future expected β coefficient, the Valuer applies the Blume adjustment to the β coefficient estimated using historical data.

The adjustment approach and method proposed by Blume are as follows:

βa = 0.35+ 0.65 βh

Where: βais the adjusted beta value, and βh is the historical beta value.

ComparableCompany
Company A	0.7795	15	%	4.74%/95.26%	0.7479
Company B	0.8388	25	%	9.98%/90.02%	0.7744
Company C	0.8169	15	%	21.02%/78.98%	0.6662
				Average:	0.7295

Average Unlevered β

Based on the target capital structure of 11.91% and an income tax rate of 25%, the Levered β for TuXi Xiamen is 0.8035. After Blume adjustment, the adjusted β is 0.8723.

SpecificRisk Return

The Capital Asset Pricing Model (CAPM) is generally considered a tool for estimating the return on a portfolio. Since the CAPM cannot directly estimate the return on a single company, and given that the investment risk of a single company is generally considered higher than that of a portfolio, the return on a single company or stock should account for the excess return generated by all the specific risks unique to that company relative to the portfolio.

The specific risk premium primarily reflects the risk premium or discount associated with the non-systematic, specific factors unique to a company. The Valuer determines the specific risk premium through a comprehensive analysis that considers the company’s risk characteristics, size, business model, stage of development, core competencies, and dependence on key customers and suppliers, combined with the evaluator’s professional experience and judgment.

Expected Return on Debt

Expected return on debt is, in essence, the expected rate of return sought by debt investors holding assets in the portfolio.

Due to differences in business conditions and capital structures, the debt-repayment capacity of different enterprises varies, and the expected rates of return for debt investors should also differ accordingly. Therefore, the expected rate of return on debt investments is closely related to the enterprise’s financial risk, specifically its capital structure.

The Valuer determines the expected return on debt by considering factors such as the asset group holder’s operating performance, capital structure, credit risk, collateral, and guarantees, and by adjusting the loan prime rate (LPR) published by the National Interbank Funding Center as a baseline.

Value of Non-Operating Assetsand Liabilities (including surplus assets) ΣCi

Non-operating assets and liabilities refer to assets and liabilities that are unrelated to the production and operations of the subject entity and are not included in the enterprise’s projected free cash flows after the Valuation Benchmark Date.

Surplus assets refer to assets that exceed the entity’s operational needs as of the Valuation Benchmark Date and are not included in the entity’s projected free cash flows after the Valuation Benchmark Date.

For non-operating assets and liabilities (including surplus assets), the cost approach is used in this valuation.

Value of Minority Interest

The value of minority interest is determined based on the book value as of the Valuation Benchmark Date.

Based on the above parameters, the equity value of TuXi Xiamen under the income approach is derived as follows:

Item
Value of operating assets (sum of discounted free<br> cash flows)	3,217.3
Less: Interest-bearing debt	(80.0	)
Add: Surplus funds	541.3
Add: Net value of non-operating assets and liabilities	(72.2	)
Less: Minority interests	(3.9	)
Total equity value of TuXi Xiamen (income approach)	3,610.0
